Update: They did come back out and sealed around where the radon
fan goes into the basement floor. However, I also had an issue with the
underground connection outside. While they were good enough to connect
the pipe system to the downspout in that corner, they did so in a way
where it is not sealed. So some water gushes out and up right next to
the house. I have called three times about this, starting at least a
month ago. Twice they never got back to me. One time they did, asked
that I email a picture, which I did immediately. Then I never heard back
again. At this point, I give up and not going to waste time calling
them again. Ill try to deal with it myself.

There has also been a
few cracks in the cement they put down in the basement. Nothing major
though, but I didnt expect cracks within the first month or two.   They
also had a major crack during the work in one of the cement wall blocks
at floor level.  Its right behind where they put the wall guard thing so
its going to be difficult for me to fix. They shouldve fixed this while
they were doing the work.

While overall I was initially pleased
with their work, but the things mentioned above they overlooked or just
dont respond to when i make mention disappointed me. If you choose them,
be vigilant with any issues you have while they are there.



Joe,  the salesman was excellent and not pushy or gimmicky like other basement waterproofing salesmen.  Explained what they recommended well.  The foreman,  I'm bad with names and don't remember it,  seemed very knowledgeable and was professional and nice,  though I must admit he was very hard to understand as he had a strong  accent. 
I was initially irritated as I had thought they were going to arrive between 8 and 9 am the first day and I didn't receive a call.  They showed up close to 11. They quickly got to work and did a great job.  Though one spot they had broken a piece of a bottom concrete block on the wall and didn't patch it up.  Granted I may cover the wall eventually with a vapor barrier before finishing the basement,  I think it would've been better if they patched it. 
My initial plan was for them to have the sump discharge towards the back of my property,  the Foreman talked me into going about 10 or so feet toward the front of my house instead.  His reasoning made sense as the area I had picked would've had water spill onto my neighbors property,  however my plan was to eventually extend it even further back myself after I cleared out some small trees.  My worry with his location is that a major rain or snow melt will result in a lake in my front yard too close to my house.  For the time being,  I'll see how it works out.  I may move it myself in the future if my worries turn out right. 
I'm a little confused on how long I should wait to move stuff back against the walls.  Joe had told me a month while the foreman said 5 or 6 days.  I'd rather know for certain what the safe time frame is,  so I don't ruin the new concrete. 
Overall,  nice clean job and the pumps work very well.  I have more water entering the basement than I thought,  as the pumps kick on twice an hour or so. 


Update: I may have to call them up and have them come back. I have a radon fan going underground. I've found that they didn't completely seal around it when they put down the new concrete.

Sump Pump Installation FAQs, answered by experts

There are a couple of similar alternatives you may consider for a sewage ejector pump, including a grinder pump or a submersible sump pump. Submersible sump pumps protect your home from flooding from outside water, though, rather than handling wastewater from inside. A grinder pump macerates, or shreds, solid waste before pumping it onward to the sewer line.

First, you can try unplugging the two sump pump cords, one for the motor and one for the float switch, then plugging them back in to reset the sump pump. You can also reset the sump pump by turning it off and back on at the breaker. Many sump pumps have a reset button, which you can press and hold for a few seconds to reset the device.

Common problems include motor failure, clogged discharge lines, and float switch malfunctions. Regular maintenance prevents many issues.

Inspect the pump annually, test the float switch, and clean the discharge line to ensure efficient operation.

Sewer ejector pumps need to be cleaned at least once a year by a professional. You shouldn’t attempt to clean it yourself because it can release sewer gasses that are toxic to humans and can be fatal. But to keep the system as clean as possible between professional inspection and cleaning services, be sure to only flush human waste and toilet paper. Avoid flushing items that can clog the system, like paper towels, grease, oil, or menstruation products.
